Improvement in horseshoes



NITED STATES 4PATENT 'Felon IMPROVEMENT IN HORSESHOES.

Specification forming part of Letters Patent No. 58,573, dated October` 9, 1866.

` To ail whom it may concern:

Be it known that I, HALsEY H. BAKER,

of New Market, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in Horseshoes; and I do hereby declare that the following is a full, clear, and exact description of the same, referencer being had to the accompanying drawings, making a part of this specitication, in which- Figure l is an inverted plan View of a horseshoe constructed according to my invention. Fig. 2 is a central vertical longitudinal section of the same. Fig. 3 is a vertical transverse section taken in the line x of Fig. 1, and representing the toe-calk of the shoe, the said portion being shown in an inverted position. Fig. 4 is a vertical longitudinal section of the heel-calks of the. shoe, also in an inverted position. j

Similar letters of reference indicate corresponding parts in all the figures.

This invention consists in a novel construction of calks and means of securing the same to horseshoes, whereby the ealks may be very easily and firmly secured to or removed from the shoes, whether the said shoes are attached to the horses hoofs or removed therefrom, and whereby the calks are rendered much less lia.- ble to slip upon stone, ice, or other smooth surfaces than those hitherto devised.

To enable others to understand the nature and construction of my invention, I will proceed to describe it with reference to the drawings.

A indicates the shoe, in the bottom or under side of which, at those points where it is desired to' secure the calks, are formed rectangular sockets a, each 'one of which is surrounded by a downwardly-projecting iiange, b. rIhe forward side or portion of that iiange which surrounds the socket of the. toe-call; is made much thicker than the three remaining sides thereof, as shown more clearly in Fig. 2.

The ends of each of the sockets a are recessed or hollowed out underneath the ends of the flanges b thereof, so as to form recesses, as shown at c, while the innermost edges of the aforesaid ends of the flanges b, which constitute the lowermost sides of the said recesses e, form square shoulders, as shown at b. Extending from each of the recesses c ofthe toecalk to the outer side of the end of the iiange b, adjacent thereto, is a hole or opening, e. One of the recesses c of each heelcalk is also furnished with a like hole or opening. (Also marked c in the drawings.)

Formed in the bottom of each socket a are two or more downwardly-projecting wedgeshaped projections, j', which extend entirely across the said sockets in a position parallel with the ends of the sockets.

Placed upon each of the iianges b, as shown more plainly in Figs. 2, 3, and 4, is a collar, B, which may be made of malleableized cast iron. The collar B of the toe-calk is furnished around its circumference with an upwardlyprojecting rim, g, which is fitted upon the periphery of the iiange I), as shown in Fig. 3. I n the collars B of the heel-calks the sides of this rim are removed; but the ends thereof iit over the ends of the iiange b, as shown at g in Figs. 2 and 4.

Projecting upward from each end of the central space or opening of the collar B, inside of the iiange b, is a tongue, It, upon the upper or extreme end of which, and placed at right angles to the said tongue 7L, is an outwardly-projectin glip or spur, t'. WV hen the collarB is iirst placed upon the iiange b these tongues h are bent inward in the manner shown in dotted lines in Figs. 3 and 4. The ends of the 'rim g of the collar B of the toe-calk are notched, as shown at j, in order that they may not cover' or interfere with the openings e in the ends of the Bange b. Furthermore, interposed between the collar B and the flange Z) is a layer or thickness of sheet india-rubber or other suitable elastic material, as shown at m in Figs. 2 and 3, and the office of which is to deaden or relieve the jarring of the horses hoof when the shoe strikes the ground or pavement, and thus prevent the injurious effects of such jarring upon the same.

Formed centrally upon one of the inner sides of the fia-nge b and the socket a of the toe-calk is a vertical inwardly-projecting rib, (shown in dotted lines at u in Fig. 25) and formed transversely within the collar B, at the corresponding central part thereof, is a par tition, r, which extends upward to the top of the socket when the collar B is placed upon the iiange b, as just described, and occupies the space between the rib n and the opposite inner sides of the aforesaid fiange and socket. The collar B being fitted upon the iiange b, with the tongue h bent inward, as shown by the dotted lines in Fig. 3, and as hereinbefore explained, the filling of the calk is driven into the receptacles formed by the space within the interior of the collar B. This'filling may consist of a block of wood driven endwise into the said receptacle, as at C in Figs. l, 2, 3, and 4. As the block is driven in it forces the tongues 7L outward, so that the lips lthereof are pushed into the recesses c, being thus hooked upon the shoulders b of the flange b.

' rlhe inner end of the block C, striking upon the wedgcfshaped projections f, is split or divided,

so that the inclined sides of the said projections force the sides of the block outward tightly against the tongues h, thus not only firmly wedging them in their places, but also, by expanding and thus tightening the upper or inner end of the block or filling in the receptacle just named, more firmly secures the said block therein.

D represents two sharp steel spurs or ice` ca-lks, which are designed to assist the calks just described in holdin g upon ice, and are simply steel wedges placed in vertical tapering holes in the forward portion of the collar B of the toe-calk, and with their broad upper or inner ends resting against the flange b, when the aforesaid collar B is secured in place. The ice-calks D, being thus dovetailed into the collar B in front of the toe-calk proper, render the shoe less liable to slip on ice, inasmuch as they penetrate deeper into the same than the other calks of the shoe. It should be mentioned that the partition r in the toecalk is somewhat thinnerthan the rib u, so that the friction of the corners of the said rib upon the case s or other filling of the said calk tends materially to retain the same in place, at the same time that the partition, being snugly fitted into its place, prevents any rocking or displacement of the collar B by the strain exerted upon it during the drawing by the horse of heavy.

formed by the ends of the fibers of wood enable it to adhere better to stone or other smooth surfaces than if made of metal, and thus more effectually prevents the slipping of the shoe upon such smooth surfaces.

When it is desired to detach the calks from the shoe without removing the shoe from the hoof, the filling is dug out or otherwise removed, anda punch is then inserted in the opcnin g or openings e, 1and driven inward until the lips t' are forced out of the recesses c and away from the shoulders b', whereupon, in the case of the toe-calk, the collar B may be drawn out with the fingers 5 but with the heel-calks, inasmuch as but one of the tongues h is driven inward, the said collar B is wrenched or turned over with a pair of nippers, which draws the lip of the other tongue out of its recess c. In case the shoe is already detached from the hoof, the filling may be most conveniently removed fromthe calks by burning it out, when the collar B may be removed therefrom in the same manner as just described.

What l claim as new, and desire to secure by Letters Patent, is-

1. The attachment of the collar B to the shoe A bymeans of lips formed upon the tongues h ofthe said collar, hooked upon the shoulders b by the driving into its place of the filling of the calk, substantially as herein set forth, for the purpose specied.

2. The wedge-shaped projections f, so arranged in combination with the tongues 7L and lips t of the collar B as to insure the rigid locking of the lip'i upon the shoulders b by the act of driving the filling of the calk into its place, substantially as herein set forth, for the purpose specified. y

3. The opening` or openings e, so Aarranged in relation with the shoulders b and with the tongues 7b and lips t' of the collar B as to enable the said lips t' to be disengaged from the shoulders b', substantially as herein set forth, for the purpose specified.

4. The ice-cal ks D, arranged in relation with the collar B and with the wood or other suitable filling ofthe calks, substantially as herein set fort-h', for the purpose specified.

5. The combination of the layer or thickness m of india-rubberor other elastic material with the collar B and shoe A, substantially as herein set forth, for the purpose specified.
